According to Instagram, when you enable two-factor, “every time you log into Instagram from an unknown device you’ll be asked to enter an SMS security code or backup code in addition to your username and password.”

To enable two-factor within Instagram for iOS, tap on the Settings icon in the top right, then scroll down and tap Two-Factor Authentication. Next, enable ‘Require Security Code’. You’ll be asked to enter a phone number, then a number will be sent to you via text message, where you’ll enter it to confirm and tap ‘Next’. You’ll need a confirmed number to setup two-factor.

When two-factor is enabled, you’ll also want to save your backup codes in a safe place, so you can still login if you don’t receive an SMS security code during the authentication process.

If you’re using any service online that offers two-factor authentication, I strongly recommend enabling it. Save your backup codes within 1Password for iOS so you’ll never lose them.

Instagram also announced today they will start blurring “sensitive content” to make their community safer.
